[commit] Zap ecs.stepping_through_sigtramp

[Andrew Cagney <cagney at gnu dot org>]

Hello,

This removes the `struct execution_control_state' field 
stepping_through_sigtramp.  Since its never set or referenced there's no 
sense in keeping it.

An obvious follow-through is to also drop it from the save/load thread 
state methods.

committed,
Andrew

2004-08-25  Andrew Cagney  <cagney@gnu.org>

	* infrun.c (struct execution_control_state): Delete field
	"stepping_through_sigtramp".
	(init_execution_control_state): Do not set same.
	(context_switch): Do not pass same to save_infrun_state and
	load_infrun_state.
	* gdbthread.h (struct thread_info): Delete field
	stepping_through_sigtramp.
	(save_infrun_state, load_infrun_state): Delete parameter
	stepping_through_sigtramp.
	* thread.c (load_infrun_state, save_infrun_state): Update.
